SebArt professional line The real plane SF260TP S 50E ARF scale ASSEMBLY MANUAL The SIAI-Marchetti SF260 is an Italian light aircraft marketed as an aerobatics and military trainer. It was designed by Stelio Frati, originally for Aviamilano, which flew the first prototype of it on July 15, 1964. Actual production was undertaken when SIAI Marchetti purchased the design soon thereafter and continued with this firm until the company was bought by Aermacchi in 1997. The military versions are popular with smaller air forces, which can also arm it for use in the close-support role. The design employs a low-mounted cantilever wing and retractable tricycle undercarriage, and is often praised for its sleek lines and sporty appearance. The pilot and up to two passengers are accommodated under a broad, extensively glazed canopy. The structure is approved for acrobatics. SF260TP version, first flown in 1980, was using an Allison 250-B17D turboprop. General characteristics: Crew: One pilot + two passengers Length: 7.1 m (23 ft 0 in) Wingspan: 8.35 m (26 ft 11.75 in) Wing area: 10.1 m² (109 ft²) Empty weight: 765 kg (1,488 lb) Powerplant: 1 Allison 250-B17D turboprop Performance: Maximum speed: 441 km/h (236 knots, 276 mph) Range: 2,050 km (1,107 NM, 1,274 mi) Service ceiling: 5,790 m (19,000 ft) Armament: Two under-wing hard points, each can carry 300 kg (661 lb)
The model The SIAI-Marchetti SF260TP S 50E ARF scale, was designed by the 15 times Italian Champion Sebastiano Silvestri, vice-european Champion and 2 time F.A.I World Cup winner F3A. This professional ARF kit is the result of Sebastiano s long research, experience in F3A and his passion for scale planes. This combined with an extremely light weight structure and with many small aerodynamical tricks give the SF260TP S 50E an impressive precision and easy control at any airspeed and flight condition. The SF260TP S 50E can do it all it can start and land very easy on grass surface and with the factory installed electric retractable landing gear, light system, flaps, looks very scale on ground and in the air. The SF260TP S 50E is ready for any pattern maneuvers as for unbelievable easy rolls, knife-edge pass, loops, spins, stall turn... and almost anything else you can dream up from a scale plane are waiting you!...the only limit is your fantasy!

Radio set up Light system
The factory provided light system is ready to use, just assemble it as per the photoinstructions and plug the lead in a free port of the receiver and it will work as preprogrammed. Electric landing gear and Steering wheel servo The factory assembled electric retractable landing gears and doors are ready for use: Connect the all 3 landing gear Let gears work with channel 5-GEAR on your favorite switch on your radio Use a standard setting Travel Adjust on gear channel (+100% to -100%) Connect the steering wheel servo lead with an Y with rudder servo, or (better) use an extra channel just for the steering wheel function linear mixed with rudder, that will activate only with landing gear out. Flaperon We recommend this function to do your starts and landings shorter and easier. Activate the FLAPPERON function in your radio Use two separate channels to let work the two aileron servos, as per your radio s instruction manual Use flaps 60% down, both ailerons 20mm down Combine with flaps down an aileron differential of 60% (more up). Control throws For the AILERON we recommend the following throws: High rate: 35 UP, 30 DOWN left & right NOTE: Use aileron differential if you have a programmable radio. Normal flight: D/R: 60% Expo: 20% aerobatics: D/R: 100% Expo: 40% Start & landing with flaperon: D/R: 100% Expo: 0% For the ELEVATOR we recommend the following throws: High rate: 30 up & down Normal flight: D/R: 50% Expo: 20% Aerobatics: D/R: 100% Expo: 40% Start & landing: D/R: 100% Expo: 40% For the RUDDER we recommend the following throws: High rate: 30 left & right Normal flight: D/R: 80% Expo: 20% Aerobatics: D/R: 100% Expo: 30%
Start & landing: D/R: 100% Expo: 30% Note: the Expo is (+) for JR systems, and ( ) for Futaba systems. Mixing We recommend the following mix (if you have a programmable computer radio): Rudder Elevator UP full rudder to the right, the elevator have to go up (positive) approx. 6% full rudder to the left, the elevator have to go up (positive) approx. 6% Recommended Center of Gravity The recommended CG is 110mm behind the leading edge of wing. Pre-flight Never attempt to make full throttle dives! This model have to be flown like a fullscale airplane. If the airframe goes too fast, such as in a high throttle dive, it may fail. Throttle management is absolutely necessary. Range test your radio Before fly, be sure to range check your radio as manufacturer s instruction manual of you radio-system recommend. Double-check all controls (aileron, elevator, rudder and throttle) move in the correct direction. Be sure that your motor battery pack is fully charged, as per the instructions included with your batteries and that your radio is fully charged as per its instructions. Finally... have nice flights!
